Summary :

One of the motives of recent studies for designing discrete-time impedances by using the Switched-Capacitor (SC) technology, is to simulate general impedances such as FDNR, Super-L and so on. Authors have previously proposed the Switched-Capacitor Impedance Simulation Circuit (SC-ISC)" to accomplish this purpose. In this paper, an improved version of the SC-ISC, which is based on the LDI sz transformation, is proposed, with the partly-differential structure. One of the advantages of using the partly-differential structure is that exact LDI immittances are easily obtained. Furthemore, a Lossless Discrete Differentiator is simply simulated with a LDI integrator by using the enhanced flexibility of the differential form. Furthermore, by applying the improved SC-ISC, a design technique of a new Frequency Dependent Voltage Controlled Current Source Pir (FD-VCCS-P)" is proposed. In this respect, two kinds of special FD-VCCS-Ps are investigated. Moreover, their simple applications are described, and the results of experiments and simulations are also reported.
